Directional detection of dark matter with a nuclear emulsion based detector

Cosmological observations indicate that the major part of our Universe is composed of dark matter (DM). The DM in the form of Weakly Interacting Massive Particles (WIMP) can be detected directly through its scattering inside the detector. Most direct detection experiments measure only the energy of recoiled nuclei. The NEWSdm experiment is the first directional DM search experiment with a solid-state detector: the use of nano-grained nuclear emulsions both as a target material and as a nanometric-resolution tracking device will enable overcoming the so-called neutrino floor and will provide an unambiguous proof of the galactic origin of DM.
